Knapp had spent 2 1/2 season as Detroit’s pitching coach after replacing the fired Chuck Hernandez.

The Tigers are 45-40, leaving them just a half-game back of Cleveland in the AL Central, and they just had both Justin Verlander and Jose Valverde named to the AL All-Star team, but they do rank 12th in the AL with a 4.40 ERA, leaving them ahead of only the Orioles and Royals. Verlander is the team’s only starter with a sub-4.00 ERA.

Max Scherzer’s inconsistency and the lack of development from former first-round picks Porcello and Ryan Perry could have been factors in the dismissal. Scherzer is 9-4 this season, but his ERA stands at 4.90 following another poor outing Saturday. Porcello is at 4.96. Perry, who was drafted with expectations that he’d emerge as a closer down the line, has an 8.20 ERA in 18 2/3 innings this season.

Brewers’ right-hander Phil Bickford received a 50-game suspension after testing positive for a drug of abuse, per the Los Angeles Times’ Bill Shaikin. This is the second time Bickford has been suspended for recreational drug use, as he was previously penalized in 2015 after testing positive for marijuana prior to the amateur draft.

Bickford was selected by the Giants in the first round of the 2015 draft and was later dealt to the Brewers for lefty reliever Will Smith at the 2016 trade deadline. He finished his 2016 campaign in High-A Brevard County, pitching to a 3.67 ERA, 10.0 K/9 rate and 5.0 BB/9 over 27 innings.

Two other suspensions were handed down on Friday, one to Toronto minor league right-hander Pedro Loficial for a positive test for metabolites of Stanozolol and one to Miami minor league outfielder Casey Soltis for a second positive test for drugs of abuse. Loficial will serve a 72-game suspension, while Soltis will serve 50 games. All three suspensions are due to start at the beginning of the 2017 season for each respective minor league team.

We are very disappointed to learn of Phil’s suspension, but we fully support the Minor League Baseball Drug Prevention and Testing Program and its enforcement by the Commissioner’s Office. Phil understands he made a mistake, and we fully anticipate that he will learn from this experience.

Confirming a report from Tuesday, the Diamondbacks officially signed right-hander Fernando Rodney to a one-year, $2.75 million contract on Friday. The 39-year-old stands to receive up to $4 million in incentives, per Jack MacGruder of FanRag Sports, with $250,000 kicking in when the veteran reaches 40, 50 and 60 appearances and $500,000 if he reaches 70.

Rodney came three games shy of the 70-appearance mark in 2016 during back-to-back stints with the Padres and Marlins. He put up a cumulative 3.44 ERA on the year, which effectively disguised the extreme split during his performances in San Diego and Miami. The Diamondbacks aren’t anywhere close to contending in 2017, but Rodney should stabilize the back end of their bullpen while providing Arizona GM Mike Hazen with a potential trade chip during next year’s deadline.

With Fernando, we’re getting an established Major League closer and a veteran presence in the bullpen. It is helpful to have someone with his experience on the back end to slow the game down and get the final three outs.
